| Zusammenfassung | The nonlinear dielectric response of low-energy excitations in glasses is investigated on the basis of the two-level tunneling model (TM). It appears that the TM has sufficient flexibility to explain the low-temperature dielectric response of glasses, at least qualitatively. An explicit analysis of experimental data obtained on borosilicate glasses leads to a low-energy cutoff Δ 0 min/ k ≈ 3 mK in the density of tunneling states. |
